Importância da avaliação do ciclo de vida na análise de produtos: possíveis aplicações na construção civil

Much has been discussed lately about reusing waste in new construction materials and countless studies have been carried out based on this objective. However, before these products can be called “sustainable” and a recycling system can be effectively implemented, it is fundamental for all the aspects involved in this action to be understood, and more important, what are the true gains for the productive sector and what are the benefits for the environment if this was to occur. In order to obtain a general framework for all environmental aspects and potential impacts associated with these products, over their entire life cycle, the most appropriate methodology is the Life Cycle Assessment (LCA). In view of the above, the objective of this work is to provide an overview of current studies of LCA, its history, its importance, its standards and the methodology employed and its applications related to civil construction. It is expected, to obtain a more complete scenario of the influences from a study of LCA, as well as establishing a contribution for the assessment of specific products and processes for civil construction, disseminating the importance of the use of this tool within the sector.

Representaciones de la Guerra Civil en el diario El País : 1986, 1996, 2006

El lenguaje es siempre valorativo, aún cuando adopte formas aparentemente objetivas o neutras. Esta conjetura básica guía el análisis comparativo de diversos artículos aparecidos en el diario El País en los meses de julio de 1986, 1996 y 2006 en ocasión de los aniversarios del inicio de la Guerra Civil española (50, 60 y 70 años respectivamente). La intención es indagar qué versiones de la guerra ofrece cada uno y cuáles son las estrategias discursivas que utilizan para hacerlo. Es decir, cómo construyen una representación de ese acontecimiento fundamental en la historia de España y qué diferencias encontramos en el tratamiento discursivo que hacen de él. Se analizan algunas opciones discursivas que son claves en la construcción del referente: la selección temática y lexical, las expresiones que aluden a la guerra y la gramática particular que exhibe u oculta los participantes de las acciones. El hecho de que sea el mismo periódico nos autoriza a suponer que las diferencias lingüísticas e ideológicas que encontremos en la comparación responderán a cambios en las representaciones sociales de las cuales los medios son vehículos privilegiados. De este modo, el análisis luz sobre las transformaciones que la memoria de la Guerra Civil española sufrió en los últimos veinte años.

Structural behaviour and design criteria of under-deck cable-stayed bridges subjected to seismic action

Under-deck cable-stayed bridges are very effective structural systems for which the strong contribution of the stay cables under live loading allows for the design of very slender decks for persistent and transient loading scenarios. Their behaviour when subjected to seismic excitation is investigated herein and a set of design criteria are presented that relate to the type and arrangement of bearings, the number and configuration of struts, and the transverse distribution of stay cables. The nonlinear behaviour of these bridges when subject to both near-field and far-field accelerograms has been thoroughly investigated through the use of incremental dynamic analyses. An intensity measure that reflects the pertinent contributions to response when several vibration modes are activated was proposed and is shown to be effective for the analysis of this structural type. The under-deck cable-stay system contributes in a very positive manner to reducing the response when the bridges are subject to very strong seismic excitation. For such scenarios, the reduction in the stiffness of the deck because of crack formation, when prestressed concrete decks are used, mobilises the cable system and enhances the overall performance of the system. Sets of natural accelerograms that are compliant with the prescriptions of Eurocode 8 were also applied to propose a set of design criteria for this bridge type in areas prone to earthquakes. Particular attention is given to outlining the optimal strategies for the deployment of bearings

Survey on integration of Applied Geology and Geomorphology in Civil Engineering curricula in the framework of the European Higher Education Area (EHEA) by using practical trips

The engineer must have sufficient theoretical knowledge to be applied to solve specific problems, with the necessary capacity to simplify these approaches, and taking into account factors such as speed, simplicity, quality and economy. In Geology, its ultimate goal is the exploration of the history of the geological events through observation, deduction, reasoning and, in exceptional cases by the direct underground exploration or experimentation. Experimentation is very limited in Geology. Reproduction laboratory of certain phenomena or geological processes is difficult because both time and space become a large scale. For this reason, some Earth Sciences are in a nearly descriptive stage whereas others closest to the experimental, Geophysics and Geochemistry, have assimilated progress experienced by the physics and chemistry. Thus, Anglo-Saxon countries clearly separate Engineering Geology from Geological Engineering, i.e. Applied Geology to the Geological Engineering concepts. Although there is a big professional overlap, the first one corresponds to scientific approach, while the last one corresponds to a technological one. Applied Geology to Engineering could be defined as the Science and Applied Geology to the design, construction and performance of engineering infrastructures in and field geology discipline. There has been much discussion on the primacy of theory over practice. Today prevails the exaggeration of practice, but you get good workers and routine and mediocre teachers. This idea forgets too that teaching problem is a problem of right balance. The approach of the action lines on the European Higher Education Area (EHEA) framework provides for such balance. Applied Geology subject represents the first real contact with the physical environment with the practice profession and works. Besides, the situation of the topic in the first trace of Study Plans for many students implies the link to other subjects and topics of the career (tunnels, dams, groundwater, roads, etc). This work analyses in depth the justification of such practical trips. It shows the criteria and methods of planning and the result which manifests itself in pupils. Once practical trips experience developed, the objective work tries to know about results and changes on student’s motivation in learning perspective. This is done regardless of the outcome of their knowledge achievements assessed properly and they are not subject to such work. For this objective, it has been designed a survey about their motivation before and after trip. Survey was made by the Unidad Docente de Geología Aplicada of the Departamento de Ingeniería y Morfología del Terreno (Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos, Universidad Politécnica de Madrid). It was completely anonymous. Its objective was to collect the opinion of the student as a key agent of learning and teaching of the subject. All the work takes place under new teaching/learning criteria approach at the European framework in Higher Education. The results are exceptionally good with 90% of student’s participation and with very high scores in a number of questions as the itineraries, teachers and visited places (range of 4.5 to 4.2 in a 5 points scale). The majority of students are very satisfied (average of 4.5 in a 5 points scale).

Nonlinear models for lateral dynamics of railway vehicles on bridges subject to wind action

The study of lateral dynamics of running trains on bridges is of importance mainly for the safety of the traffic, and may be relevant for laterally compliant bridges. These studies require threedimensional coupled vehicle-bridge models, wheree consideration of wheel to rail contact is a key aspect. Furthermore, an adequate evaluation of safety of rail traffic requires nonlinear models. A nonlinear coupled model is proposed here for vehicle-structure vertical and lateral dynamics. Vehicles are considered as fully three-dimensional multibody systems including gyroscopic terms and large rotation effects. The bridge structure is modeled by means of finite elements which may be of beam, shell or continuum type and may include geometric or material nonlinearities. The track geometry includes distributed track alignment irregularities. Both subsystems (bridge and vehicles) are described with coordinates in absolute reference frames, as opposed to alternative approaches which describe the multibody system with coordinates relative to the base bridge motion. The wheelrail contact employed is a semi-Hertzian model based on realistic wheel-rail profiles. It allows a detailed geometrical description of the contact patch under each wheel including multiple-point contact, flange contact and uplift. Normal and tangential stresses in each contact are integrated at each time-step to obtain the resultant contact forces. The models have been implemented within an existing finite element analysis software with multibody capabilities, Abaqus (Simulia Ltd., 2010). Further details of the model are presented in Antolín et al. (2012). Representative applications are presented for railway vehicles under lateral wind action on laterally compliant viaducts, showing the relevance of the nonlinear wheel-rail contact model as well as the interaction between bridge and vehicle.

A ação direta da vítima contra a seguradora nos seguros facultativos de responsabilidade civil na dogmática brasileira

A investigação parte do surgimento histórico do contrato de seguro, abordando em sequencia sua teoria geral e a dogmática brasileira pertinente para, após, traçar os contornos específicos do contrato de seguro de responsabilidade civil, tanto pelo viés doutrinário quanto da legislação vigente no Brasil, dando ênfase maior ao seu conceito e finalidade social, às peculiaridades de seu sinistro, assim como à pluralidade de interesses nele albergado, afastando-se a ideia de se tratar de um seguro de reembolso, e adotando-se sua conceituação como de um seguro de garantia. Após, são fixados os conceitos básicos de processo civil aplicáveis ao objeto do estudo: jurisdição, processo, ação e seus elementos, para somente então expor o surgimento e desenvolvimento teórico da ação direta da vítima contra a seguradora na doutrina e jurisprudência francesas, passando pelas fases exegética, legalista e doutrinária de sua análise. Com base neste desenvolvimento histórico, adota-se concepção da ação direta da vítima contra a seguradora como instituto jurídico de conformação própria, oriundo dos princípios de equidade e justiça, e destinado ao afastamento dos princípios gerais de direito civil da relatividade contratual e da igualdade entre credores, constituindo meio de exercício do direito próprio da vítima contra a seguradora do causador do dano. Delimitados os conceitos em estudo, são expostas algumas experiências estrangeiras acerca do uso da ação direta e, partindo-se do embasamento teórico do seguro de responsabilidade civil e da ação direta da vítima por este protegida, ingressa-se na análise de seu desenvolvimento na dogmática brasileira. Para tanto, volta-se à ideia do seguro de responsabilidade civil como seguro de reembolso, e aos argumentos dela decorrentes para afastar o cabimento da ação direta, tais como o princípio da relatividade contratual, a ausência de previsão de solidariedade entre segurado e seguradora, e as dificuldades de exercício da ação e também de defesa por parte da seguradora e do segurado. Expostos e criticados os argumentos contrários ao cabimento da ação direta, passa-se ao estudo das tentativas doutrinárias e jurisprudenciais, no direito brasileiro, de se fornecer à vítima um meio de exercício de sua ação contra a seguradora, inicialmente por instrumentos de processo civil, e terminando por se reconhecer a possibilidade de acionamento conjunto de segurado e seguradora pelo Superior Tribunal de Justiça na sua Súmula 529. Por último, são tratados os argumentos doutrinários e legislativos favoráveis ao cabimento da ação direta da vítima contra a seguradora em qualquer seguro de responsabilidade civil, com e sem a participação inicial do segurado no processo, com destaque à função social do contrato de seguro de responsabilidade civil facultativo e ao direito próprio da vítima perante a seguradora. Conclui-se, assim, que a ação direta da vítima contra a seguradora, em qualquer seguro de responsabilidade civil, é instrumento apto e cabível na dogmática brasileira para dar vazão aos preceitos de equidade e justiça, despersonalizando a responsabilidade civil, ao levar seu foco da imputação para a indenidade, respeitando ao duplo interesse do moderno contrato de seguro de responsabilidade civil, e solucionando pela via mais apta e simples situação complexa.

The EU-Ukraine Action Plan on Visa Liberalisation: an assessment of Ukraine's readiness. OSW Commentary No. 45, 2011-01-17

The Action Plan on visas adopted during the recent EU-Ukraine summit is a success for Ukraine. It is the first time that Kyiv has succeeded in obtaining a definition of the conditions and criteria whose fulfilment will enable Ukraine to apply for the lifting of EU visas for its citizens. Ukraine's strong point has been its political will; the lifting of this visa regime has been a priority for all Ukrainian governments since 2005. Since Viktor Yanukovych became president, Ukraine has adopted or prepared key legal acts that brought it nearer to European standards in the area of border and migration management. One of Kyiv's strengths is also its relatively well reformed and efficiently managed border service. Moreover, illegal transit migration via Ukraine is decreasing, and fewer Ukrainians are trying to enter or stay in the EU illegally. Also, Kyiv has efficiently implemented the EU-Ukraine readmission agreement. The hardest task for Ukraine will be to meet the EU’s expectations concerning values, the condition of Ukrainian democracy, and the rule of law. Corruption remains the main barrier to Ukraine's development and modernisation; the courts are weak and the judicial system inefficient. The main undertaking of the new migration service that is being formed at the moment will be to create a civil system of registration, monitoring and regulating the stays of foreign nationals. This may prove difficult, as the supervisory authority (the Ministry of the Interior) remains an unreformed, police-type bureaucratic institution. Ukraine is lagging behind countries such as Russia, Belarus and Moldova when it comes to the introduction of biometric documents. Another problem is the lack of an electronic information system on foreign nationals, visas and border crossings which would be accessible to all the relevant services and institutions. For these reasons, the complete abolition of visas seems to be a longterm perspective, especially considering that many EU countries, which themselves are faced with the problem of migrants’ integration, are rather sceptical about the further liberalisation of movement of people with their eastern neighbours. In the immediate future, if Ukraine meets some of the requirements set by the EU, it will be able to seek the extension of the visa facilitations that have been in operation since 2008.

Patterns of civil society after authoritarianism: a comparison of Portugal and Spain, 1970s-2000s. CES Papers - Open Forum #17, 2013-2014

In this paper we argue that patterns of civil society in post-authoritarian democracies are the result of divergent pathways to democracy. Through a comparison of contemporary Portugal (social revolution) and Spain (reform), we show that revolutionary pathways to democracy have a positive impact on the self-organizing abilities of popular groups, thus also contributing to a higher quality of democracy. There are three mechanisms in social revolutionary processes that contribute to this. The first stems from the fact that the masses are the key actor in the revolutionary transformation process, with the power to shape (at least partially) the new rules and institutions of the emerging democratic regime. This results in greater legal recognition and institutional embeddedness between civil society organizations and the state, making it easier, in turn, for resources to be transferred to those organizations. Secondly, as a result of changes to the social and economic structure, revolutions engender more egalitarian societies. Likewise, citizens are given more resources and capacities for collective action. Finally, revolutions tend to crystalize a political culture between elites and the masses in which the principles of egalitarian participation and social change through the action of the people are accepted. This all leads to greater opportunities, resources and legitimacy for the civic action of the common people during the subsequent democratic regime.
